How to remove every other letter from a string: 

```python 
>>> 'abcdefg'[::2] 
>'aceg'
```

To remove all characters after a specific character/substring from a string, you must use the str.replace() method in Python 3.+: 

```python 

list_str = {'Abc.ex', 'Bcd.ex', 'cde.ex', 'def.jpg', 'efg.jpg'}
new_set = {x.replace('.ex', '').replace('.jpg', '') for x in list_str}
print(new_set)

```

output: 
```
{'Bcd', 'Abc', 'cde', 'def', 'efg'}
```

Can also use str.removesuffix('suffix') method which will remove suffix if there is one, and if there isn't will return original word:

```python
text = 'Quickly'
print(text.removesuffix('ly'))
print(text.removesuffix('World'))
```

output: 

```
Quick
Quickly
```
the partition method was introduced in python 2.5 and can also be used to get rid of a section. 

```python 
text = 'text.com/yes/?/noandifwillthisbethere'

head, sep, tail = text.partition('?')

print(head)
```
output: 
```
text.com/yes/

```
